On CAPS, 83% of the 77 members who have rated Broadsoft believe the stock will underperform the S&P 500 going forward. These bears include All-Star kinosternon and fellow Fool Sean Williams (TMFUltraLong), the fourth-ranked member in all of CAPS.

Late last month, kinosternon touched on Broadsoft's seemingly unsustainable price run: "Looks like the momentum investors ran this one up in a big way. Kudos to [Broadsoft] for their great quarter and strong outlook, but I think those momentum investors will start taking profits soon."

Since Broadsoft's expectation-crushing quarter in early November, its shares are up more than a whopping 150%. Currently, Broadsoft even trades at a substantial forward P/E (44.8) premium to rivals Alcatel-Lucent (16.2) and Cisco (10.4), as well as other voice plays such as Polycom (Nasdaq: PLCM) (20.0) and 8x8 (Nasdaq: EGHT) (16.0).

CAPS All-Star TMFUltraLong elaborates on the bear case:

Unless Broadsoft is planning on trouncing estimates next quarter by roughly 200%, then this is significantly overvalued. 18 times book value, 7 times sales and up a staggering 200 % in less than a few weeks. I really don't see any differentiating factor that makes [Broadsoft] better than say Polycom (Nasdaq: PLCM) in the VOIP space but hey, the market is fickle right. Technical and fundamentals agree [it's] time to hide your kids, this could get ugly.
